[0002] Sewage refers to the discharged water from life and production that is polluted to a certain extent. It is mainly the water used in life. It contains more organic matter and is easier to treat. From the perspective of the source of sewage, sewage can be defined as liquid or water carrying waste mixed with groundwater, surface water and blizzards discharged from residential, institutional, commercial or industrial areas. Sewage treatment equipment is generally required during the sewage treatment process.

[0003] When using existing aeration devices for sewage treatment, the aeration heads are mostly installed and fixed by threaded connection and bolt connection. The subsequent disassembly and replacement are cumbersome and inconvenient. Workers need to use handheld tools for installation and disassembly. The process is time-consuming and easily affects the progress of sewage treatment. Utility Model Content
